PRESSURE-RE GULATOR.

The present improvements are applicable' to the types of pressure-regulators shown in my two former patents No. 723,118, dated March 17, 1903, and No. 757,590, dated April 19, 1904.

One object of the present invention is to so construct the upper portion of the pressure cylinder that it may be made of standard or uniform size for connection ,to various sized valves; and a further object is to so construct the device that the valve will not only be accuratelyy guided by aguide carried by the piston but will also be readily removable independently of the piston and the upper parts of the apparatus whenever it is desired tore-grind the valve on its scat, as more fully hereinafter set forth.

The valve a is forced upwardly against its seat by a spring b which bears against a screw-plug c carried by a plate d removably bolted'to the under side of the valve casing and forming the bottom of the valve-casing. By removing this plate d the valve may be withdrawn downwardly out of the casing to enable the valve or its seat to be cleaned or re-ground. A stem e rises centrally from the f valve and has its upper end slidably socketed in a depending sleeve carried by the pistonf, this sleeve working freely through anopening in the top of the valve-casing, and this top portion of the valve-casing being provided with suitable openings g to permit the outgoing fluid to passup under the piston. By thus employing a sleeve-like guide on the piston arranged to work through a guideopening in the top of the valve-casing and in telescoping the upstanding stem e into said sleeve it will be observed that both the piston and the valve will be accurately and freely guided while at the same time each is removable ildependently of the other for the purposes of repairing and cleaning. The piston f Works only in the lower portion h Iof the cylinder mounted on the top of the valvecasing, this lower portion being formed in-l Specication of Letters Patent.

ing to the chamber under the regulating dia- The upper half 7c of thecylinder is smaller in diameter than the lower half and is provided with an annular flan Zat its lower end which extends outwar ly and is bolted down on top of the lower portion of the cylinder. The upper end of the cylinder is closed by a head m which is `clamped in lace by a screw-cap n, this cap also clamping in place the diaphragm o, which diaphragm is normally pressed downwardly in the usual manner by means of a suitable spring-actuated disk p carrying a pin g depending through the center of the diaphragm and the center of the headm. `Suitable adjustable devices are carried by the cap 'n to vary thepressure on the diaphragm through theI niedium of said disk Pivotally suspended from )lugs de )ending from the head m is a bell-crank lever, one arm r of which extends horizontally inward and is adapted to receive the downward thrust of the pin Q, and the other arm s of which depends from the pivotal support and is adapted to bear against the inwardlyphragm.

'extendingstem of the controlling-valve t working 1n a horizontal p'ort in the side wall of the cylinder portion 7c. Said ort communicates with an extension i o the inlet passage t'. The valve t is guided by an extension Workingin a plug u screwed into a nipple formed von the side of the cylinder 7c, this plug containing a spring which norinally closesvalve t. This arran ement of the control-valve .takes it out of t e main inlet passage and enables it to be gotten at much more conveniently than in my former patented constructions, and besides the inlet passage i, i', may 'be made smaller in diameter and thus enable the wall of the cylinderl to be made stronger.

It will be observed thatthe forcing down of the pin q Will cause the bell-crank to open the control-valve, and as the depending arm of thebell-crank is shorter than the horizontal arm the valve will be actuated quickly. This location and arrangement of the bellcrank lever for communicatinor motion from .the diaphragm to the controlling-valve is a very durable and accurate device.

By making the fessure cylinder of two parts horizontally c ivided and confining the operation of the piston to the lower section and housing theo erating arts entirel in the upper section, am ena led to attac 'to any sized valve a standard sized upper portion. This is a great advantage as nearly all the Working parts are carried by the upper portion f the c linder and I am thus required to manu ecture and carry m stock onl one size of this upper portion.

- av' thus y described'my invention,

what I c aim as new, 'and desire to secure by Letters Patent, is l `A` LIin a pressure-regulator, the combinae passage into the cylintion of a valve, a pressure cylinder mounted on the casing thereof and having an inlet passage extending up into the Wall of the .lin er. anda horizontal ort leading from er, a horizontally Worcontrolling-velve in seid port, a plug remova 'ly ly secured in the side of seideylinder essere valve, a s ri =ectuated in e cndin through the ea of the oylin er, abe l-cran pivotally depending from said head and havmg one arm in engagment with said de-l pending pin and the ot er arm; engaging with the inner endV of the control-valve.
